PU LVERIZING-MACHINE.

SPECIFICATION -formingpart of Letters Patent No. 719,503, dated February 3, 1903.

Application filed September 21,1901. Serial No. 76,118. (No model.)

1'0 wZZ whom, it may concern.-

Be it known that I, LEROY S. PFOUTS, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Pulverizing-Machines; and I do hereby declare that the following is a full, clear,'

and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the figures of reference marked thereon, in which-- Figure 1 is a top view. Fig. 2 is a sectional view on line 2 2, Fig. 3. Fig. 3 is a section taken on line 3 3, Fig.1. Fig. 4 is a side elevation. Fig. 5 is a view showing a portion of the base and one of the standards and illustrating the slot in the standard, together with one of the clamping-bolts. Fig. 6 is a view of one of the end plates, showing the back thereof and illustrating the ears, the pivoted arms, and the rods.

The present invention has relation to pulverizing machines; and it consists in the different parts and combination of parts hereinafter described, and particularly pointed out in the claim.

Similar numerals of reference indicate correspondingparts in all the figures of the drawings.

In the accompanying drawings, 1 represents the power-shaft, which power-shaft is properly journaled to the tops or upper ends of the uprights 2, which uprights are securely connected in any convenient and wellknown manner to the bed or base 3, which bed or base is formed of sufficient strength to properly support the different parts of the pulverizer and at the same time providing a strong and rigid base for the machine proper.

Upon the power-shaft 1 are mounted the pinions 4, which pinions are securely at'- tached to the power-shaft 1 in any convenient and well-known manner. To the power-shaft 1 are also mounted and securely attached the fiy-wheels 5, said fly-wheels being located and arranged substantially as shown in the drawings and should be of sufficient weight to give the desired amount of momentum to the machine.

It will be understood that the power-shaft should be extended so as to provide room for properly connecting a driving-wheel, which may be either a belt or cog, as desired. This that it is a common construction and forms .no part of the present invention, except that some manner must be employed for communicating power.

The cross-shaft 6 is properly journaled to the base 3 or to proper blocks fixed to the base, to which cross-shaft are attached in any convenient and well-known manner the wheels 7, which wheels mesh with the pinions 4, as illustrated in the drawings.

Upon the cross-shaft 6 is mounted the crushing-roll 8, which crushing-roll is formed of any desired diameter, reference being bad to the size and capacity of the machine designed to be constructed.

In the drawings I have illustrated the crushing-roll properly formed solid; but this is not absolutely necessary, as it may be formed hollow and provided with spokes or webs; but to carry out the object and purpose of the present invention the periphery of the crushing-roll should be provided with a smooth surface or a roughened one, reference being had to the kind of work designed to be performed.

To the power-shaft 1 is connected the eccentric 9, upon which eccentric is located the usual eccentric band 10, which band is preferably formed in two sections or halves,which are properly connected together, the lower section or half having connected thereto or formed integral therewith the pitman 11, which pitman extends downward and is pivotally connected to the rock-arms 12, to which rock-arms is connected or formed integral therewith the oscillating crushing-jaw 13, which crushing-jawis mounted upon the shaft 14,which shaft is properly journaled or mounted upon suitable supports 15, which supports are adjust-ably connected to the base 3 and are so connected for the purpose of bringing the oscillating jaw to or from the crushingroll 8, so as to provide for crushing material to different degrees of fineness, as it will be understood that all material passing between the crushing-roll 8 and the oscillating jaw must be brought to a fineness corresponding with the distance between the periphery of the crushing-roll and the face of the crushing-plate 16,

which crushing-plate is connectioo ed to the oscillatingjaw substantially as illustrated in the drawings.

The crushing-plate is provided with the curved or convexed surface portion 17, which curved or con vexed portion is located directly opposite the crushing-roll 8.

For the purpose of bringing the working faces of the crushing-roll and the crushingplate in better operative position the crushing-jaw 13 and the crushing-roll 8 should be journaled in the same horizontal plane.

For the purpose of providing proper supports for the shafts 6 the standards 18 are provided, and for the purpose of tying the standards 18 and the standards or supports 15 together and removing the strain during the time material is being pulverized the tierods 19 and 20 are provided, said tie-rods being provided with screw-threaded ends to receive suitable screw-threaded nuts 21. The tie-rods 19 also serve the purpose of holding in proper position the crushing or pulverizing block 22, which crushing-block is located directly above the crushing or pulverizing roll 8. The working face of the stationary crushing-block is provided with a plane face, as illustrated in the drawings, which face is located directly opposite a straight face of the crushing-plate 16, said stationary block and the straight face portion being located directly opposite each other and are so located for the purpose of partially pulverizing the material before it passes between the surfaces of the pulverizing-roll 8 and the convexed surface of the plates 16. I

It will be understood that the crushingblock 22 should be concaved upon its bottom or under side, so as to fit the crushing-roll 8, as illustrated, and for the purpose of holding the crushing-block in proper relative position it should be located against the standards 18, it being understood that the crushing-block should extend across the machine. The object and purpose of extending the pitman 11 downward and connecting the bottom or lower end to the rock-arms 12 is to impart an oscillating movement to the crushing-jaw 13 and at the same time so connect the eccentric 9 to the pitman that a vertical reciprocating movement will be imparted to the pitman and a rocking movement to the arms 12, by which arrangement all horizontal vibration is removed from the frame of the machine, this being a very desirable feature, owing to the heavy work to be performed by the machine, and removing all sudden horizontal jars.

It will be understood that the force of the eccentric in operating the oscillating jaw is up and down and not horizontal, and consequently the horizontal thrust is removed. This up-and-down thrust is brought about by extending the arms 12 from the oscillating jaw under the crushing-roll 8 and connecting the pitman to the free ends thereof. Another advantage of this construction is that by providing the arms 12 and locating them as shown a greater amount of leverage is provided, by which arrangement the direct thrust is removed from the eccentric, thereby decreasing the wear'of the eccentric and at the same time increasing the power of the machine, which allows the material to be reduced to any degree of fineness desired without'horizontal vibration.

For the purpose of properly inclosing the ends of the crushing-roll, the oscillating jaw, and the crushing-block the side plates 23 are employed, and they are provided with the ears 24, to which are pivotally connected the arms 25, said arms being located upon the collars 26, saidcollars being located upon the tierods 19 and 20 and are held ment by means of the set-screws 27. It will be understood that by my peculiar arrangement of connecting the side plates 23 they can be brought to or from the ends of the crushing-roll, the oscillating jaw, and crushingblock and can be easily removed or set from the ends of said parts for any desired purpose.

It will be understood that the crushing-cylinder is to be given a continuous rotation, and by providing the oscillating jaw the crushingplate will move with the crushing-roll when moving in one direction and will move against the rotation of the crushing-roll when moving in the opposite or return motion, by which arrangement an alternating motion is imparted as between the two grinding or pulverizing faces.

The bottom or lower portion of the standards 15 are provided with the slots 15 and are held at the desired point of adjustment by suitable bolts 15, which bolts pass through the base 3.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a pulverizing-machiue a rotating roll, an oscillating jaw having a portion extended below the axis of the jaw and located at one side of the vertical axial plane of the rotating roll, right-angled arms or extensions extending from the oscillating jaw beyond the vertical, axial plane of the rotating roll, and a pitman connected to the free end of the extended arm, and means for reciprocating the pitman.

In testimony that I claim the above Ihave hereunto subscribed my name in the presence of two witnesses.

LEROY S. PFOUTS.
